To all whom t may concern.'

Be it known that I, JOSEPH LEE ROUSSEAU, a citizen of the United States,residing at Brooklyn, inthe county of Kings and State of New York, have`invented certain new and useful Improvements in Type or Matrices, ofwhichthefollowing is aspecification, reference being had therein to theaccompanyassembled iii-line, and then presented to a mold, wherein theslug or linotype is cast, after which they are' distributed and returnedto the magazine from which they started.

Under modern conditions, it is common to employ matrices of large sizeor of great thickness, such, for'instance, las those formed with headletter or display characters. In the use of Such thick matrices, it isfound that their' great weight causes undue wear on their toothcombinations and on those on the distributer bar, as well as wear onother parts -of the machine due to their` violent impactfthereon. Inorder to relieve the partsfofsuch excessive wear, the matrices'heretofore have ordinarily been constructedin skeleton form,f or morespecifically, longitudinal cuts or grooves have been made in their sidefaces to remove as much metal as'possible. As a result, otherdiiiculties arise,- and particularly in that the necessary7` support istaken awayfrom the front edges of the matrices, wherein the formativecharacters are located, and further there is the liability that thewalls may sink or fall inwardly, causing'the matrices to lose theirproper rectangular form, so that they will fail to lock up properly inthe assembled line or fit closely against the mold when presentedthereto. Various other diliiculties will be obvious to those skilled inthe art.

It is the aim of'my present invention to4 avoid the above objections orany liability thereto, and to this end Ipropose to cut or hollow out themain portion of the matrix lying between its side walls, so that 1nother respects it will retain its ordinary form and Specification. ofLetters Patent.

contour. In other words, I form the matrix with an interior channel orcavity which will lie between/and be inclosed by its side I walls, sothat the latter may give firm support to the front edge of the matrixcontaining the formative cavity, and so that the general .form andconfiguration of the matrix may be preserved. In short, thisconstruction will not only permit a great reduction in the weight of thematrices but at the same time will maintain their proper shape and size.

I have illustrated my invention as applied to a very large or thickmatrix of the display variety, but obviously many changes and variationsmay be made in the mode of application and also in its size and form,which will still be comprised within the spirit of my invention.Similarly, the invention may ber-adapted to type or dies as well asmatrices.

Generally speaking, I desire it to be understood that I do not limitmyself to any specific form or embodiment, except in so far as suchlimitations are specified in the claims.

Referring to the drawing: Figure 1 is a perspective viewof4 the matrixconstructed in accordance with my invention; Fig. 2 is a verticalsection; Fig. 3 is a section on the line 3-3 of Fig. 2; and Fig. 4 is amodification.

In the drawing, I have'shown a vmatrix A of the general constructiondisclosed and Y also provided in its front edge with the formativecharacter A4.

Referring to Figs.. 1, 2 and 3, it will be noted that the matrix A isbored or hollowed out both from its top and bottom edges to produceellipsoidal channels or cavities, B and B1, extending longitudinallythereof and separated by an intermediate horizontal wall or partitionB2, located behind the formative character A4. As a result of thisconstruction, the side walls or faces of the matrix remain unimpaired,the above mentioned channels being located between and incloscd by them.Also7 the weight of the matrix is greatly reduced, without taking endwith a longitudinal cut or notch A5,

opening into the interior channels B or C, and designed to cooperatewith the fixed stop in the distributer box as the matrix is liftedtherefrom for delivery to the distributing mechanism, as well understoodin the art.

It will be noted (see Fig. 3) that the interior channels are so formedand located so as to reduce the opposite'side wall of the matrix at itsupper end as at A7, to allow it, when lifted, to pass the iixed stopjustre.- ferred to. The longitudinal notch: and the interior channel of thematrix thus serve conjointly "to, make up the so-called sepa-- ratingnotchl which is present inthe common form of matrices. Heretofore theseseparatingy notchesuhave been formed by means of a rotary ksaw having aconsiderable radius, and have consequently acquired great extent inmatrices of substantiall thickness, extending practically throughouttheir length and resulting in an appreciable weakening.

' This weakening becomes quite serious in connection with thethickermatrices and principally those having head-letter or display characters,because the notches are not only necessarily of greater vdepth andlength, but

in addition such large matrices have coin-l monly been formed with otherlongitudinal notches or grooves to remove as much metal as possible tolighten them. These objections are overcome inthe present formr ofmatrix, in that the longitudinalcuts orI4 `notches A5 are only of .suchextent as is necessary to allow thefmatrices to clear theI overlyingstop rail during their detachment from the line, the notches being ofsmall and uniform` extent throughout the set or -font and therebyavoiding the weakening of the matrix bodies. In addition, themanufacture of the matrices is materially facilitated, the interiorcavities Bor C usually first being drilled therein from one end or theother, and the cut or notch A5 next cut through the side wall by meansof a suitable tool such as a milling or planing tool or the like; and ifdesired, an air blast may be employed during the slotting process toblow off the chips, the interior cavities furnishing a good exittherefor and greatlyy facilitating the operation. Thematrices may thusnot only be formed with `separating notches of the short and uniform'length described, but' their manufacture may be materially simplifiedandthe expense correspondingly reduced.

The matrix is also provided at its lower 4 i edge with a cut or notch A6passing transversely through its side walls and designed to coperatewith a font selecting bridge, in the well known manner. seen that theinterior channel of the matrix in no way affects` the user of the notchbut rather serves conjointly Vwith such notch to It will be thus permitthe proper coperation'of the matrix ,Y

with the font selectingbridge.

As previously stated, I have shown my in' vention only in preferred formyand by way of example, and as applied to a specific style` of matrix.However, ymany modifications" and alterations therein, and in its modeoflf application. will readily suggest themselvesl to those skilled inthe art, without departure from its scope. l

Havingrthus described my,'inventio1`i,"its" t construction and modeofioperation, what I claim and desire to secure by Letters Patent of theUnited States is, as follows:

l. A typeor matrix of rectangular el011` vgated form containing aformative character support from its edge wall containing the formativecharacter.

2. A type or matrix of rectangular elongated form containing a formative.character in one of `its vertical edges and provided.y

at its upper end with a distributing combifnationA and on its oppositeedges with proliecting ears to adapt it 'for circulation in atypographical machine, the said type or matrix having 4solid `or rigidsideyand edge,y

walls and :formed with two longitudinal channels or cavities ylocatedbetweenand inclosedby said wallsand extending from its top and bottom.respectively, and separatedA .I

by an intermediate partition which is v1o-4 cated in the'rear of theformative character,"

whereby the matrix is materially lightened 12o. vwithout weakening it,without destroying its x Y general form or contour, and without remov-Af ing the support from its edge wall containing the formative character.

y3. A type or matrix adapted forcirculation in a typographical machineand formed at its upper end with a channel or cavity located between andinclosed by its side walls, one of said walls being reduced at its upperend by said channel, and the ,other formed the channel, the said cavityand With a longitudinal cut or notch opening into notch thus servingconjointly to provide a separating notch adapted to coperate with thestop rail of a distributor boX used in said typographical machine,substantially as shownand described.

4. A type or matrix A. adapted for circulation in a typographical.machine and formed with a channel or cavity located between andinclosed by its side and edge Walls and opening at its bottom, the saidtype or matrix being formed .in its bottom with a cut I or notchextending transversely through said JQSEPH LEEROUSSEAU.
